l 1 MIXING DE ICE FOR LIQUID runrnnsmunnrs.

Application filed February 8, 1926. Serial No. 86,918.

This invention relates to mixing devices especially adapted'for mixing various liquid refreshments.

Briefly stated, an important object of the invention is to provide simple and reliable means whereby one or more drinks may be expeditiously mixed by the operation of a single lever which will obviate the need of employing an electric motor as is now so generally done.

Another object of the invention is to provide a mixer for liquid refreshments which is attractive, durable, and comparatively cheap to manufacture.

Other objects and advantages will be apparent during the course of the following description In the accompanying drawing forming apart of this application and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a perspective of the improved mixer.

Figure 2 is a vertical sectional view through the same. v

In the drawing, wherein for the purpo e of illustration is shown a preferred embodiment of the invention, the numeral 5 designates a hollow base mounted upon legs 6 and supporting inner and outer tubular standards 7 and 8, respectively. The upper tubular standard may have an ornamental exterior, and as shown in Figure 2, supports a housing 9 of substantially disc shaped formation.

In carrying out the invention a plurality of spindles 10 extend downwardly from the housing 9 and are provided at their lower portions with suitable agitators adapted to be received in cups 11, the cups being adapted for the reception of the ingredients of a liquid refreshment. Suitable bearing casings 12 extend downwardly from the housing 9 and are provided with anti-friction elements 14 by means of which the friction incident to the turning of the spindles 10 is reduced to a minimum.

The upper portions of the spindles 10 have keyed and slidable connection with tapered friction wheels 16 adapted for driving contact with the beveled edge of a main driving disc 18. The driving disc 18 is keyed or otherwise rigidly connected to the upper portion of a main driving shaft 20 extended through the housing 8 and having with the teeth of a ratchet wheel 28. The

ratchet wheel is keyed or otherwise connected to theshaft 20. i

It is important to note that a driven gear 30 has rigid connection with the driving cup 24 and is in constant engagement with a main driving gear 32 mounted upon a stub shaft extended through the bottom of the base 5 and carrying a small spur gear 34. Figure 2 illustrates that the spur gear 84 is in mesh with the teeth of an 'arcuate rack or gear segment 36 on'the forward rigidly portion of a manually operated lever 38.

The lever. is fulcrumed as indicated at 39 and is provided with a handle at. the rear end thereof whereby the operator may rock the lever and bring about the turning of the gear 30, the cup shaped driving member 24, the shaft 20 and associated elements at a very high speed. As previously stated. when the parts are-thus set in motion the balance wheel 24 serves to continue the ro tation of the motion transmitting mechanism until the same has spent itself. 7

. With reference to the foregoing description it will be apparent that the manual operation of the lever 34 will bring about the turning of the agitators or spindles 10 for the mixing of the liquid refreshments in the cups 10. .It will be observed that each cup 11 is provided with an attaching member or strap 40 having what might be said to be a socket or opening for the reception of the upstanding end 41 of a lever 42 which lever 42 is fulcrumed intermediate the ends thereof to a bracket 46 carried by the tubular standard 7. Therefore when a cup 11 is at tached to the outer portion of one of the levers 42, as shown in Figure 1, the inner portion of that lever is moved upwardly to overcome the tension of a coil spring 47. When the lever 42 is thus operated by the weight of the cup 11 and the contents of the same, a link 50 engaged with the inner Figure 2 illustrates that each spindle is provided with a coil spring 60*which ex erts tension on the driven wheel to hold the same in frictional Contact with the driving disc 18. However, the strength ot the spring -17 is great enough to normally overcome the strength of the spring 60 and consequently the wheel 16 is normally out of driving engagement with the Theref r Q th hpnh at h (o the s p 1 to t lever {12 will result the mo enient of the outer portion of the lever 55L downwardly so hat he sp ng; 13 m y chin into i p ay an h reh es h h a 'ri ihs ehs s ih ht h veen t e d h 18 and he asi ath h sul o th s is tha t e .as tie e $1.0 n turn unti teams ave been Pr perly p: plied. "This is an i nportant feature of the invention since the agitators are not turn ing during the application of the cup. This would he inconvenient for the reason that h i hth ht to be mix w uld p hha ly e sp lle 91 th? he ht ih rhy e orsours p par to y to e a ph tien O 9, r .19 16 of t e p h shaft 20 is set motion by theleverSS and is continued in motion by the balance wheel 22. i s g Having thus described the invent-ion what iS claimed A e shm nt P1 1 fil6 i0 ommi ing base, a standard mounted thereon, a
